Low Delay COFDM Digital Wireless Video Transmitter and Receiver HD 10km NLOS
COFDM Digital Transmitter Feature:
Introduction:
DSHDT20WG is a new arrival digital wireless video audio transmitter
which adopts the latest technologies of COFDM modulation and
H.265/H.264 image compression that enables good NLOS (Non line-of
-sight) transmission with DVD quality video. The transmitter is
compact size with strong power amplifier for longer-range
transmission.Good heat resistant with three cooling fans. Be safety
with AES128/256bits. Work well in fast-moving transmission and
obstruction environment.
